99% sure this is an interference engine, almost every engine now a days is, to squeeze as much power out of it as possible while complying with emissions. The compression test showed no compression, right? If you put some oil in the cylinders and the compression bumps up you know its piston rings and if it doesn't change the problem is in the valves.
